CUSHION.

Speccation of Letters Patent.

Patented Apr. 19, 1910.

To all whom 'it may concern:

Be it known that I, FRANK P. DARGY, a citizen of the United States,residing in the city and county of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Cushions, of which thefollowing is a specification.

This invention relates to improvements in cushions.

The main objects of this invention are: First, to provide an improvedcushion adapted to aiiord a suitable cushion or spring support forpersons of different weight. Second, to provide an improved springcushion in which the metal parts can be readily shipped in theknock-down and quickly and easily assembled by the user or by thecushion manufacturer. Third, to provide an improved cushion having metalspring supports in which the upholstering is effectively supported sothat the wear thereon is minimized. Fourth, to provide an improvedspring support in which coiled springs are embodied in which suchsprings are so supported that they are held in an erect position and arenot likely to become displaced. Fifth, to provide an improved cushionstructure which is economical to produce and at the same time is verystrong and durable.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecication, in which,

Figure l is an inverted plan of a structure embodying the features of myinvention, one of the spring supports being broken away. Fig. 2 is anenlarged detail vertical section taken on a line corresponding to line9.--2 of Fig. l. Fig. 3 is a detail section taken on a linecorresponding to line 33 of Fig. 2. Fig. 4 is an enlarged detail takenon a line corresponding to line 4 4 of Fig. 1, showing means forsecuring the coiled springs to the top or plate spring. Fig. 5 is anenlarged detail cross section, taken on a line corresponding to line 55of Fig. 2, showing the` means of securing the bottom of the coiledsprings to their supports. Fig. 6 is an inverted plan of a plurality ofthe spring supports 4 with the springs 3 secured therein, nestedtogether for shipping. Fig. 7 is a side elevation of a plurality ofplates 8 nested for shipping.

In the drawing, the sectional views are` taken looking in the directionof the little arrows at the ends of the section lines, and similarnumerals of reference refer to similar parts throughout the severalviews.

Referring to the drawing, I provide a frame preferably consisting of theside pieces 1 and end pieces 2, this being the general form of carriageand car seat cushion frames. The coiled springs 3, which are preferablyof the helically-coiled type, are arranged 'in series, as illustrated.These springs are provided with suitable supports, as 4, preferablyformed of strips of sheet metal having their edges turned in, as at 5,to clamp the bottom coils of the springs, thus rigidly securing themtothe supports.

The supports are preferably provided with hangers (3 at each end adaptedto rest on the top of the frame, as illustrated in Fig. 2. These may beperforated at 7 to receive nails or brads, if desired, but I find thisis not necessary in practice with the parts assembled as I illustrateherein.

Each series of springs is provided with a top plate 8 having springengaging tongues 9 on the under side thereof, by means of which thesprings are effectively secured to the plates. These tongues arearranged so that the springs may be readily secured thereto, and beremoved, should occasion require. This I accomplish by directing aportion of the set of tongues for each spring' inwardly and a portionoutwardly,that is, in the same general direction, so that the springsmay be readily slipped under the tongues. The tongues are punched downfrom the plate and have sufficient spring tension therein to readilysnap over the top coils of the springs. Other means might be providedfor securing the springs to the top plates. These top plates arepreferably formed of spring sheet metal and provided with downturnedends l() adapted to engage the grooves or kerfs 1l formed in the upperedges of the side pieces of the frame. These grooves or kerfs arelocated adjacent to the outer sides of the side pieces so that the topplates effectively support the upholstering well out toward the edge ofthe cushion, as clearly appears in Fig. 2. The downturned ends of thetop plates are preferably slotted at 12 to receive the screws 13, whichare arranged through the side pieces, as indicated by the dotted linesin Fig. 2. This prevents the lateral movement of the top plates, andalso supports the side pieces so that they are not likely to split offfrom the kerf, thus making it possible to locate the same close to theedge and continuous, which, it is obvious, is a convenience inmanufacturing.

The springs 3 are adapted to support the spring plates S in an elevatedposition7 so that the springs 3 normally carry the entire load. As soon,however, as these springs are overcome suiiiciently to carry the topplates down until their end pieces 10 engage the bottom of thegrooves-which serve as stops or rests therefor,-the spring plates arebrought into action and help to carry the load. The spring plates arespaced somewhat, but are arranged close enough together to form asuitablel support for the upholstering. This may be a paddedupholstering, as illustrated, or the spring structure forms a suitablesupport for a ratan covering, or any suitable fabric.

In the structure illustrated, I show a padded covering consisting of aninner fabric 14 and an outer fabric 15, between which is a filling 16.YThe edges of the inner and outer fabrics are preferably brought downover the sides of the frame and secured on the lower edge thereof bymeans of the facing strips 17, thus forming a structure which has a verycomplete and attractive appearance. The top plates for the springs, asstated, effectively support the upholstering so that it is very durable.They also effectively support the same well out to the edges of thecushion, which is a further advantage as will be obvious.

The springs 3 are so supported that it is practically impossible forthem to become displaced in use. At the same time, they may be readilyassembled by the user or the cushion manufacturer.

By forming the parts as I have illustrated, the metal parts can bereadily shipped in the knock-down in a nested form, as illustrated inFigs. 6 and 7, and this results not only in an economy of storage andpacking space, but as well in rates to be secured thereon.

I have illustrated and described my improved spring support in detail inthe form preferred by me on account of its structural simplicity andeconomy and the convenience with which it may be assembled. I am aware,however, that it is capable of considerable variation in structuraldetails wit-hout departing from my invention, and I desire to beunderstood as claiming t-he same specifically, as illustrated, as Wellas broadly.

- Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
